Aluzinc Steel Coil

Aluzinc Steel Coil

Galvalume Steel Coil Aluminum-Zinc Plated Steel Sheets Have A Characteristic Smooth, Flat And Ornate Starburst Surface With A Silvery-White Base Color. The Coating Composition Consists Of 55% Aluminum, 43.4% Zinc And 1.6% Silicon By Weight. The Production Process Of Al-Zinc Plated Steel Sheet Is Similar To That Of Galvanized And Aluminized Steel Sheet, Which Is A Continuous Melt Coating Process. 55% Al-Zinc Alloy Coated Al-Zinc Plated Steel Sheet Has Superior Corrosion Resistance Compared To Galvanized Steel Sheet Of The Same Thickness When Exposed To The Same Environment On Both Sides. 55% Al-Zinc Alloy Coated Al-Zinc Plated Steel Sheet Not Only Has Good Corrosion Resistance, But Also Has Excellent Adhesion And Flexibility.

Galvalume Steel Coil Manufacturer

BOMIS is a Chinese galvalume steel coil manufacturer. We have the ability to supply AZ20-150g/square meters, alvalume to meet customers’ requirements for use in highly corrosive areas. We ensure that the weight of the metallic coating does not cut corners, and we have the equipment to detect it.

Feature

Galvalume steel coil has good corrosion resistance. It can balance the protective and repair effects of zinc with the anti-corrosion effect of aluminum, extending the service life of steel sheets.

Galvalume steel coil has relatively good heat resistance and will not change color when exposed to temperatures of around 316 degrees for a long time. It still has good antioxidant properties at a temperature of 677 degrees.
